Connecting Cables
Now that the processors are installed, the next step is to connect the cables to
the serverboard. These include the data (ribbon) cables for the peripherals and
control panel and the power cables.
Connecting Data Cables
The cables used to transfer data from the peripheral devices have been carefully
routed in preconfi gured systems to prevent them from blocking the fl ow of cooling
air that moves through the system from front to back. If you need to disconnect
any of these cables, you should take care to reroute them as they were originally
after reconnecting them (make sure the red wires connect to the pin 1 locations).
If you are confi guring the system, keep the airfl ow in mind when routing the
cables. The following data cables (with their serverboard connector locations
noted) should be connected. See the serverboard layout diagram in this chapter
for connector locations.
DVD-ROM Drive cable (IDE#1)
Control Panel cable (JF1, see next page)
SATA cables, 6015B-NTR/6015B-NT only (SATA0 ~ SATA3)
SGPIO cable, 6015B-NTR/6015B-NT only (SGPIO1 to SATA backplane)
Connecting Power Cables
The X7DBU has a 20-pin primary power supply connector designated "JPW1" for
connection to the ATX power supply. Connect the appropriate connector from the
power supply to JPW1 to supply power to the serverboard. See the Connector
Defi nitions section in this chapter for power connector pin defi nitions.
In addition, your power supply must be connected to the 4-pin Auxiliary ATX Power
connection at JPW2 and the 8-pin Processor Power connector at JPW3.
Connecting the Control Panel
JF1 contains header pins for various front control panel connectors. See Figure
5-1 for the pin locations of the various front control panel buttons and LED indi-
cators. Please note that even and odd numbered pins are on opposite sides of
each header.
